huashu-motion

Your coding agent makes a launch film, writes the score, and you click the frame to change it

About

Ask Claude Code or Codex for a 30 second launch film. It reads your product, offers three directions, writes the film as HTML and GSAP, composes the music in ABC notation and opens a studio in your browser. Press C, click a spot on a frame, type the change, and the agent edits only that spot. Renders MP4, MOV, GIF or WebM on your machine with no paid API. By 花叔 (@AlchainHust).

Ships the om CLI (Node 22+) that drives the Chrome you already have for stills, checks and renders, runs a local studio server on 127.0.0.1 and calls FFmpeg. bin/om falls back to npx --yes huashu-motion, which pulls code from npm at run time, and a reference note suggests yt-dlp --cookies-from-browser for grabbing video clips, which exposes your browser cookies, so skip that step unless you trust the source. Optional one-time downloads: a ~55 MB pack of CC0 and CC-BY instrument samples and, for narration, a ~325 MB Kokoro voice model. No API key or paid service. Gen Agent Trust Hub rates it high risk for these reasons, Socket and Snyk pass. Tested on macOS only so far; the Codex sandbox blocks the local preview and the browser until you approve them.
